The need to track up to a million dollars was small, sure.
But if you're revenue is based on these projects, wouldn't you want some sort of real-time counter of $$ being pledged? Maybe I'm just being a statistics nut...
Oh, don't get me wrong, I am too. But I don't know how stretched Kickstarter's team are- while I'd love to see a stats counter like that on my own project, I rarely have the time to put one together.
